Tangem Secure is a view-only crypto portfolio and tax tracker. Add a public wallet address
(Ethereum / EVM 0x… or Bitcoin) to see balances, transactions and tax estimates.
Does the app hold my funds? No. It is read-only and never asks for keys or a seed phrase.
Why are some tax numbers approximate? They depend on the available on-chain transaction history and are estimates, not tax advice.
How do I remove my data? Settings → Delete all data wipes all portfolios and cached data from your device.
